Castlereagh, now Marquess of Londonderry, was intending to attend. But in the course of the summer he fell ill from the strain of defending his policies in Parliament. He went to his country home at Cray in Kent to rest, but his condition deteriorated rapidly, and he began to show signs of derangement. His doctor took the precaution of removing his razors, but on 12 August he found a penknife, cut his throat and bled to death.
